1. Flywheel energy storage is a component with independent functions in virtual prototype technology
The function of the virtual prototype technology is to enable it to store and discharge energy, and to ensure the safety and efficiency of energy storage and discharge. In the field of flywheel energy storage design, virtual prototype technology refers to the application of three-dimensional design software in a computer to establish a prototype flywheel energy storage model and perform a series of performance simulations on it. The virtual prototype technology is to use computer simulation technology to establish a model similar to the physical prototype, and obtain the performance description of the prototype through optimization, integration and simulation testing. Virtual prototype technology is realized in the background of digital design. It relies on the accuracy and parametric characteristics of 3D digital model, so that analysis and simulation can be carried out quickly to realize the optimization of design scheme. The virtual prototype technology emphasizes the digital product model and its production process. The virtual prototype technology evolves the design concept expressed by the two-dimensional drawings into a virtual product based on the three-dimensional solid model, and establishes a digital design platform.
2. Virtual prototype technology in the establishment of flywheel energy storage model
Firstly, the working principle and structure of the existing flywheel energy storage physical model are analyzed, and the main components are measured, and then the three-dimensional solid model of each component is established by UG software. Accurate physical models and convenient modeling methods are the keys to applying virtual prototype technology. In the modeling process of each component, the virtual prototype technology is mainly used to establish functions such as sketches, forming features, free-form features and sheet metal features.
The structure of the flywheel is relatively complex and is a typical sheet metal part. The virtual prototype technology uses the UG Fanjin design module to create and make the flywheel model. General Flange feature, Sheet Metal bend feature, Sheet metal punch feature, Sheet metal bead in the Sheet Metal Feature menu , Sheet Metal Bridge (sheet metal bridge) features and other functions are widely used in the energy model of flywheel energy storage modeling, and the parametric modeling method of UG software is used to establish a parametric solid model of each component for subsequent design analysis, Modifying the model lays a solid foundation to continuously improve the design and quality of the flywheel. The virtual prototype technology assembly of flywheel energy The virtual prototype technology assembly module of UG software is used to establish the virtual prototype technology model of flywheel energy storage. After completing the establishment of the virtual prototype technology model of each component of the flywheel, the virtual prototype technology assembly can be carried out. This book adopts the bottom-up method for virtual prototype technology assembly, using pairing constraints, alignment constraints, orthogonal constraints, angle constraints, parallel constraints, center alignment constraints, distance constraints and other constraints to establish pairing conditions, so that once the virtual prototype model of the part Change, the virtual prototype technology assembly model of the product, that is, the virtual prototype technology model of the flywheel, will change with the change, and realize the real parametric design.
3. Virtual Analysis of the Flywheel
For the purpose of research and analysis, four motion analysis programs, scenario, scenarioIo2, scenario3, scenarioIo4, were established. Each analysis scheme corresponds to an assembly arrangement. If problems such as interference or too large gaps are found during the analysis, the virtual prototype technology model can be modified in time, and then the virtual prototype technology analysis is carried out until satisfactory.
